Journey of Reverso: Part 3 (Reverso Gran'Sport Chronograph)

In looking for something quite innovative, I had always thought that dual sided Reversos represented the most logical use of the Reverso case. What impressed me the most about the Gran' Sport is its uniqueness amongst Reversos. While the Squadra is proportionally (1:1.6) not a bona fide golden ratio Reverso, the Gran'Sport line is (and is the only other Reverso that bears the same proportion other than the traditional reversos. Another appeal of the watch is its size, at a modest 28.3 mm x 43.5 mm x 12.6 mm, only a hair larger than the Reverso GT I reviewed previously. The movement is an original chronograph movement and as far as i know the only dual sided chronograph.

Slightly barreled case, compared with the GT cased Reverso Duo

I can only comment on the overall experience of wearing the watch. Personally, while gold is an admirable material, the Gran'Sport is in all essence a sports watch and is better in the steel version. Although I prefer the steel bracelet for comfort, the rubber strap is a suitable match as well. The back of the case has two curved ridges that elevate the case back off the wrist for comfort. The watch wears similarly to a 38mm watch and wraps very well around the wrist. The integrated bracelet has brushed center links and polished outer links and is wonderfully comfortable with two 4mm adjustments at the clasp (standard on newer JLC sports bracelets).

The bracelet is designed with removable spring bars all along the bracelet, and the case is attached via a notched bar and a screw securing the notch which should prove more reliable than a spring bar.

Accuracy is excellent and within 1 second a day and the seconds hand glides smoothly. Chronograph pushers are not wobbly and the chronograph function works just as promised. With the possible exception of the price, it's probably the ultimate sports watch. In theory it's possible to go swimming with it but I certainly haven't tried and sometimes I wish the water resistance was a healthier 100m.
